How to implement ReplaceAll in Java...

Took a look at some snippets I wrote some time ago and found the code below. Hope my blog's readers enjoy it. It is not pure .Net code but can be converted to.

package guerche.evaristo.luciano.samples

public class ReplaceAllSample
{
  public static void main(String[] args)
  {
 String searchFor;
 String replaceWith;
    StringBuffer searchBuffer;

    searchBuffer = new StringBuffer("\tLuciano Evaristo Guerche\n\t\t\tMarcos Evaristo Guerche\n\t\t\tJuliano Evaristo Guerche");

 searchFor = "Evaristo";
 replaceWith = "E.";
    System.out.println("Before replacing = " + searchBuffer.toString());
    while (searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()) > 0)
    {
  searchBuffer.replace(searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()), searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()) + searchFor.length(), replaceWith);
    }
    System.out.println("After replacing  = " + searchBuffer.toString());

 searchFor = "E.";
 replaceWith = "Evaristo";
    System.out.println("Before replacing =" + searchBuffer.toString());
    while (searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()) > 0)
    {
  searchBuffer.replace(searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()), searchBuffer.toString().toUpperCase().indexOf(searchFor.toUpperCase()) + searchFor.length(), replaceWith);
    }
    System.out.println("After replacing  = " + searchBuffer.toString());

    searchBuffer =  null;
  }
}
